BAT-GATHERING ATTACHMENT FOR COTTON-CONDENSERS.

SPECIFICATION forming part of Letters Patent No. 271,488, dated January 30, 1883.

Application filed October 19, 1882.

T) all whom it may concern:

Be it known that I, FREDERIC 0. MANN, of East Bridgewater, in the county of Plymouth and State ofMassacbusetts, haveinvented certain Improvements in Bat-Gathering Attachments for Cotton-Condensers, of which the following'is'a specification.

This invention relates to cotton-seed linters,

gin-cleaners, or other machines in which cotton fibers are compacted and delivered in the form of a bat. r The object of the invention is to provide an attachment for machines of this class adapted to wind the batof cotton into convenient form as it passes from the machine.

To this end my invention consists in the improved attachment which I will now proceed to describe.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a side elevation of a portion ot'the condensing .mechanism of a cotton-seed linter provided with my improvement. Fig. 2 represents a top view of the same. Fig. 3 represents a section on line :c a2, Fig. 1.

. The same letters of reference indicate the same parts in all the figures.

In the drawings, A represents the perforated or wire-cloth cylinder of a cotton-condenser. B represents a pressure-roll which presses the hat of cotton against the surface of the cylinder,.said parts being journaled in a suitable frame and forming no part of my invention. The cylinder A is positively rotated in the direction indicated by the arrow, and with the roll' B is covered, as usual, by a-bonnet or casing. (Not shown in the drawings.)

in carrying out my invention I provide a loose roll, 0, adapted to bear with a yielding pressure on the cylinder A at a point in the rear of the roll B, and also adapted to be rotated by the cylinder, so as to wind upon itself the bat ofcotton passing over the cylinder, and to yield or be displaced outwardly as the bat accumulates upon it. Ijournal the roll (J in slots I l in the ends of two arms, D D, which are pivoted at E E to ears formed on clamps F F, detachably secured by set-screws G G to the frame of the machine. Said arms are adapted to rise and fall, and therefore permit (No model) the necessary displacement of the roll 0. To the under sides of the arms 1) are attached springs or yielding buffers J, which bear on the frame of the machine, as shown in Fig. 1, and prevent the arms from dropping below the position they occupy when the roll 0 is in place and bearing on the cylinder A. The roll 0 is provided with elongated journals G O, which project far enough outside of the arms D D to serve as handles for the roll as wellasjournali: 6c

The operation, is as follows: The operator rolls the end of the bat of cotton upon the roll 0 until the bat is sufficiently connected with said roll to be wound thereon by the rotation of the roll which is caused by the cylinder A. As the bat accumulates on the roll the latter is displaced outwardly, the arms D D turning on their pivots. When a suflicient quantity of cotton has been wound upon the roll 0 the operator severs the bat and removes the roll from the arms D, slips the coiled bat olf endwise of the roll, and replaces the roll in the arms D, the latter being supported by the springs J while the roll was removed, so that their slots I are in posit-ion to receive thejour- 75. nals of the roll. The rolled piece of bat removed from the roll 0 can be placed in a receptacle with other similar pieces.

I am aware that a loose accumulating-roll bearing on alarge cylinderhas been providedin 8o alapping-machine,thejournalsofsaidrollbeing adapted to play in slots formed in fixedstandards. It will be seen that by supporting said roll in arms pivoted to the frame of said ma-' chine the roll is enabled to move away from the drum with much less resistance and friction than when itsjournals movein rigid s ets..;..

I claim 1. In a cotton-condenser, the combination of the supporting-frame, the cylinder A, the arms D D, pivoted to the frame, and the accumulating-roll O,journaled in said arms and adapted to rise and fall therewith, so as to bear with a yielding pressure against the cylinder, as set forth.

2. The improved attachment for a cottoncondenser, composed of two clamps adapted to be detachably secured to the frame ofthe machine, the arms 1) D, pivoted to ears on said clamps, and the accumulating rolljournaled in 10s the outer ends of the said arms and adapted to be readily separated therefrom, as set forth.

3. The combination, with the supportingframe, of the pivoted roller-supporting arms provided with springs or yielding bufi'ers, adapted to bear on said frame and prevent said arms from falling below their proper position when the roll is removed, as set forth.

In testimony whereofl haw: signed my name to this specification, in the presence of'two sub 10 scribing Wltl'lCSSOS, this 3d day of October, 1882.
